To all whom it may concern: f Be it known that I, STANLEY H; KNIGHT, 'a Citizen of the United States of America, 'and al resident of Chicago, inthe countyo'f Cook,` State oflllinois, have vinvented certain new and useful improvements in Soda Fountains,` of which the following is a lspeci- Iication.

rlhis invention relates to that class' of soda water fountains in which a main vcooling chamber and an auxiliary cooling'chamber y adapted to contain the fruit juices andjotlier avors are associated together, with theauX- iliary chamber in superimposed andofi'set relation to the main chamber.l vAnd 'the present improvement has for its object To provide a structural 'f oifma'tion'-and parts whereby association ofv the fountain' the colder water fromthe bottom of the main cooling :chamber is fed upwardly into the auxiliary cooling chamberV or chambers to attain an eective and economical cooling of such auxiliary chambers, before such water is discharged into the waste .outlet from the fountain, all as will hereinafterr more yfully appear. Y

In the accompanying drawings :v Fig. l, is a longitudinal sectional elevation of a soda fountain structure having the present invention applied.` Y

Fig. 2, is a transverse section on line 2.-2.

F ig.` l, of the dispensing'v portion of the structure. f

Fig. 3, is a similar view on line ,L-3. Fig.

1 of the work bench portion of the structure. Like reference numerals indicate like parts in the different views.

Referring to the drawings, l designates the main casing of a soda fountain structure having its interior divided into compart-y ments adapted to contain the ice-cream tank, soda water tanks, etc., andv broken ice and water, as usual in the present class of soda fountain structure.

2 designates a flat top covering the open upper end of the casing l, and having an entrance opening closed by sliding lids as shown. f

3, -designates auxiliary cooling casings or sections arranged at the respective sides of the main casing l andhaving communication therewith in the manner hereinafter described. The casings or sections 3 have their lower portions arranged on a plane a short distance below the top portion of the of Aauxiliary' casings' 3' and above the main aforesaid casings 3, 3

' the 'lower ends main casing 1, so that witha normal level'of the cooledfluid in said main casing,a .comparatively shallow depth of such fiuid'will prevail in" saidfauxiliary casingsor sections 3, tof vmaintain Y'inl a properly 'cooled condietion jars of. syrup andi like soda-i fountain supplies, usually stored therein;`

y3 designates sa central portionfor-casing ofvthe structurer-arranged betweengthe pair casing '1,1to provide'a. supporting Vand enclosing means for the fountainfdispensing, faucets 'Tand Itheir .pipeconnections, as shown more particularly lin Fig. l.` i

In the Apreferred arrangement4 ishowny in the drawings, :the present structure isv ar-.LVV

ranged under and f behind 'the dispensingfy i counter-of a drug yorlikestore, andV the" proximately vertical lower wall 4, an inter-` mediate inclined entrance wall 5, andan will preferably vhave .a i rear odset 'formation comprising, an ap-*Yl upper approximately vertical vwall 6, as if' shown more particularlyr in Figsf2 and 3.

8 designates pipes or passages "connecting of the chambers ofjthe outer auxiliary casings 3, with the'lower portion of the chamber of the maincasing l, and adapted Vin la continued operation of the y.fountain to conduct cold water from the bottom of the chamber of the main casing lv into thechambei" of said auxiliaryA cooling nected to the chambers of the auxiliary chambers 3 .intermediate the height of. the

casings 3 as hereinafter morefullyset forth. 9 designate outlet pipes orpassagescon-4 y same and adapted'to providean outiow for ff' excess ofliquid in saidy chambers. y l0 designate' entrance openings formed,

inthe inclined entrance walls' of the auxiliary casings?) for the entry and removal and like supplies stored therein. The entrance openingfof the centrallyarranged 10U f supplyv of chipped ice with which the cooling ycham.v

auxiliary casing 3y is adapted for the convenient introduction .of the from the chambers 'of the s'yrup, fruit essence f 'i bers of the structure are supplied `vfromtinie i y to time, and to such end the open'upper portion of the casing 3 isprovided with a re-v x movable lidorcover 3. f f

11 designate work board shown in f Fig.y1.

wel

units `of any -usual detail construction varranged atv the respectivel ends of the main casing, `1 as In the present improvement the normal liquid level in the chamber ot' the main casing l is on a lerel with the upper end or the outlet. pipes or passages 9 above described, and the arrangement is such that with a gradual melting ofthe ice in said main chamber increase of water takes place in said chamber, and through the pipes or passages 8, in the chambers ot the auxiliary casings 3, and rises above the upper end ot the .outlet pipe or passages 9 to overflow through the saine into any convenient and suitable drain connection. By such opera Vtion a constant supply of very cold water is Amaintained 1n the lower portions o'l' the chambers oi' the auxiliary casings 3, in an eective and economical manner.

Having thus Jfully described my said invention what l claim-as new and desire to secure by Letters Patent vist-- l. ln a soda water Jr'ountain, the combination of a lower deep main chamber adapted to contain a cooling medium, soda water tanks and ice cream cans, a superimposed and olicset comparatively shallow auxiliary chamber providing a cooling receptacle Jfior fruit juices and the like, the lower portion of the auxiliary chamber extending below the upper portion o the main chamber, a pipe connection between the lower portion of the main chamber and the bottom of the auxiliary chamber and adaptedto convey upwardly the cold water in the lower portion of the main chamber into the bottom ot the auxiliary chamber, and an overflow pipe connected tothe auxiliary chamber at a point remote from the aforesaid pipe con* nection.

2. In a sodawater fountain the combination of a lower deep main chamber adapted to contain a coolinjg` medium, soda water tanks and ice cream cans, a plurality of superimposed and otl'set comparatively shallow auX- iliary chambers in spaced relation to each other and providing` cooling;` receptacles for fruit juices etc., the lower portions of the auxiliary chambers extending below theupper portion oit the main chamber, pipe connections between the lower portion of the main chamber and the bottom portions of vey upwardly the cold water from the lower.

vthe auxiliary chambers and. adapted to conyportion of the main chan'iber into the bot` tom portion of the auxiliary chambers, and f overflow pipes connected to the auxiliary,L

chambers remote connections.
